2 Regarding fluoroscopy time, only 29 procedures were recorded (n=29). In seven patients, there were technical problems that prevented precise measurement.

<sup>3</sup> For contrast volume, only 30 procedures were recorded (n=30). In six patients, there were technical problems that prevented precise measurement.
